When I run alda repl for the first time, or at the momet no player process existing.
It will consume 100% CPU for almost 30s.
At this time, alda repl shell has no response .

Even it report a WARN msg:

Starting player processes...
Mar 25 15:29:36 WRN repl/player_management.go:162 > No player processes availabl
e. error="It looks like Alda is having trouble starting player processes in the\
nbackground. This could happen for a number of reasons.\n\nTo troubleshoot:\n\n
 • Run \x1b[93malda doctor\x1b[0m and see if any of the health checks fail.\n\n
 • Run \x1b[93malda ps\x1b[0m to see the state of any currently running player\n
    processes.\n\n  • Look for error messages in:\n      \x1b[93mC:\\Users\\wang

 player process in the foreground:\n      \x1b[93malda-player -v run -p 27278\x1
b[0m\n\n  • Try to make it play something:\n      \x1b[93malda -v2 play -p 27278
 -c \"piano: c12 e g > c4\"\x1b[0m"

Sometimes when first start the alda repl shell,
I quickly type piano c d e f and press Enter

No sound happens, but wait for a while.

This is a bad experience. So that I wanna a long running player process before.

Is this due to wait the player process ready/active ?
and Why initialize the player process so slowly ? (big sf2 file ?)

I'm not sure, off hand, what the issue could be, but it might be related to this: #410

I think if we adjusted our JVM options, we could make the player processes more lightweight. But I'm not very knowledgeable in that area.
